I am developing an android app thap show some photos in a listview.
This is layout for each item in listview.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<ImageView
android:id="#+id/exam_page_item_imageview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:scaleType="centerCrop"/>
</RelativeLayout>
My listview displays
I want to display imageview that fits the width of device. (fit width only)
Could you give me suggestion or have any idea to resolve this problem ?
Try this :
<ImageView
android:id="#id/imgview"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:adjustViewBounds="true"
android:scaleType="fitCenter" />
android:adjustViewBounds = "true"
Will help when your images are larger than the imageview. It will not strech the image but will shrink it.
android:scaleType="fitCenter"
For times when your image is smaller than imageview, it will strech the image to the width of its parent.

I am using an ImageView and I display gifs in it. The problem is for example this gif: http://media3.giphy.com/media/110U0ZUA6mPxqE/200.gif has different dimensions than this: http://media0.giphy.com/media/10YsmVhdN1S6wE/200.gif and I display the gifs in a listview. The gif which has more or less the same height and width is shown good. But the gif which has unreasonably different width and heigt shows only a part of the gif..
This is my Item:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal">
<ImageView
android:id="#+id/imageViewGif"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:adjustViewBounds="true"
android:scaleType="fitCenter"
android:minWidth="300dp"
android:visibility="visible" />
</LinearLayout>
<ProgressBar
android:id="#+id/progressBarSearchedGif"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true" />
</RelativeLayout>
To sum up, the question is how can I show the full gif in my imageview even when the dimensions of the gifs are different.
you can try removing android:scaleType="fitCenter" , and set android:adjustViewBounds="true" to your imageview.
If you always want the entire image to display in an ImageView, you have two choices. You can either stretch it to fit the size of the ImageView with this option:
android:scaleType="fitXY"
Or you can reduce the size of the image to fit the ImageView without changing its aspect ratio:
android:scaleType="centerInside"
Refer to the javadoc for details.
Problem: trying to give multi device support screen for a simple layout but in Nexus 6 its creating the problem,means not showing fit.
It's side is cutting down where as per as docs for nexus-6 resolution is 1440*2560 and image should be in drawable-xxxhdpi .so i keep a image with resolution of 1440*2560.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/icon"
android:id="#+id/imv" />
</RelativeLayout>
if i ll give match_parent so obvious it will stretch the image.
Please help me to get out of it.
Here is screen shots of screen -

Set the width of the Image to fill_parent (you can set margins if you want a bit smaller imageView or you could also just set a fixed width)
Use android:adjustViewBounds to keep aspect ratio
Set height to wrap_content (it will take whatever it takes to maintain aspect ratio)
<ImageView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:adjustViewBounds="true"
android:src="#drawable/icon"
android:id="#+id/imv"
android:scaleType="fitCenter" />
If you want to fit the image on the imageview, replace android:src with android:background in the ImageView in the xml code.
Try to use these lines of code in the layout
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/icon"
android:scaleType="fitXY"
android:id="#+id/imv" />
I have two ImageViews with the same image source inside LinearLayout, but why the second image is smaller than the first?
This is the source code:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical">
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="center_vertical">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/background_landscape" />
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/background_landscape" />
</LinearLayout>
</RelativeLayout>
The error can be reproduced clearly on 800x1280 pixel resolution.
How can make both images have the same size with the second image cropped on the right side of the screen. (NOT SCALED DOWN)
... why the second image is smaller than the first?
Because the first image gets its real width due to wrap_content value of layout_width attribute. And the second image receives the rest width (width of layout minus width of first image) from LinearLayout, which is obviously smaller, than the real width of the image. That's why it gets scaled down.

You might use ScrollView, which allows children to go out of parent's boundaries.
Update: as mentioned by CommonsWare:
<HorizontalScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scrollbars="false"
>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:gravity="center_vertical">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/background_landscape" />
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/background_landscape" />
</LinearLayout>
</HorizontalScrollView>
Like beworker said the first image is getting its width due to the wrap_content and the second image gets the remaining available horizontal space.
Use android:layout_weight="1" in both ImageViews if you want them each to ocuppy half the available screen width
I am working on a android card view. Here is the code that I have now:
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_margin="10dip"
android:orientation="vertical"
android:background="#drawable/drawable_card_bg">
<ImageView
android:id="#+id/photo"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:src="#drawable/test_img" />
....
and the UI looks like:
However this is not what I am looking for. I want the image to be placed on top of the card, with the top, right, left margins to be 10dip from the background card boarder.
Meanwhile, I want to keep the ratio of the image, so don't want to hard-code the width/height of the image view. I want the image width to fit the width of the background card, and the height should be adjusted according to the width.
How should I change the layout parameters to achieve this?
Thank you
Add android:adjustViewBounds="true" to your ImageView in xml in order to let the ImageView adjust its bounds.
It's very easy......... please do this thing. Replace your imageview code using this one
<ImageView
android:id="#+id/photo"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:scaleType="fitXY"
android:adjustViewBounds="true"
android:src="#drawable/test_img" />
If my answer will help you then support this.
Thanks!!!
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/LinearLayout1"
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
<ImageView
android:id="#+id/imageView1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center_vertical"
android:scaleType="fitXY"
android:adjustViewBounds="true"
android:layout_x="0dip"
android:layout_y="0dip"
android:background="#drawable/mlview1" />
I'm using android emulator 2.2 . My image occupies the screen horizontally but vertically shows a large gap from the Bottom. The image size is 800X600 . should it be re-sized and then used?
Make sure that:
1. Both height and width on both parent and child is fill_parent
2. You are setting the src property and not the background one on the image
Note: You also don't need the layout_x nor layout_y
